Pregnancy is a time when the health of both mother and baby must be regularly monitored. Detailed ultrasound examinations can provide critical information about the baby's health. These examinations provide high-resolution images and can help detect potential illnesses or abnormalities in the baby at an early stage. These examinations are typically performed at specific weeks and provide important information about the baby's development and health. Performed by specialist doctors, these ultrasound examinations play a critical role in monitoring the health of both mother and baby.

Detailed ultrasound used during pregnancy is a diagnostic method that provides high-resolution images. It is performed using high-frequency sound waves that do not contain harmful radiation. While this method produces two-dimensional images similar to standard ultrasound, it provides a larger number of images. These images can then be combined using software to create three- and four-dimensional images. These detailed ultrasound methods:

• Detailed 3D ultrasound: Provides a detailed view of the baby's development and the mother's reproductive organs. It also allows for detailed examination of congenital defects and fetal problems, especially in high-risk pregnancies.
• Four-dimensional detailed ultrasound: This method is a moving version of three-dimensional ultrasound. It can create moving videos of the fetus and surrounding tissues, allowing for more detailed examination of the baby's face and movements.
• Fetal electrocardiography: This is a procedure used when a baby may have a congenital heart defect. It may take longer than a standard ultrasound and can help diagnose heart defects by providing high-resolution images of the fetal heart.
• Five-dimensional detailed ultrasound: This ultrasound method is generally a rarely used technology. Unlike other detailed ultrasound methods, it can provide true color moving images, but it is not a commonly used method and is only available in select clinics with state-of-the-art equipment.

In what situations are detailed ultrasounds performed on pregnant women?

During pregnancy, a detailed ultrasound may be preferred in certain situations to closely monitor the health of both the baby and the mother. Certain conditions and suspected problems may necessitate this detailed imaging by perinatologists. A detailed ultrasound during pregnancy may be performed for the following situations:

• Monitoring the baby's growth and position,
• Determining the sex of the baby,
• To detect multiple pregnancies (twins, triplets),
• To diagnose problems related to the condition of the placenta (the membrane surrounding the fetus),
• Checking for genetic differences (e.g., Down syndrome),
• To detect congenital anomalies,
• To evaluate the amount of pregnancy water,
• Checking the baby's oxygen intake,
• To determine the presence of a tumor in the uterus or ovary,
• Measuring the size and depth of the fetus.

Which structures can be examined with detailed ultrasound?

A detailed ultrasound is a medical imaging method used to obtain high-resolution images. This method allows for detailed examination of the baby's development and the expectant mother's condition during pregnancy. The following structures can be examined with a detailed ultrasound:

• Baby's organs and development: Baby's organs, such as the heart, brain, lungs, liver, kidneys, and digestive system, can be examined in detail. Information about the structure, development, and functions of these organs can be obtained.
• Fetal development : The baby's body proportions, bone development, muscle structure and general physical development can be evaluated.
• Placental status: The location, structure, size, and function of the placenta can be examined. This can be used to assess whether the placenta is providing adequate nutrients and oxygen to the baby.
• Amniotic fluid volume: The amount of amniotic fluid surrounding the baby can be measured. This measurement can detect any decrease or excess.
• Uterus and ovaries: The expectant mother's uterus, uterine wall thickness, tumors that may occur in the uterus, or structures related to the ovaries can be examined.
• Congenital anomalies : Signs of genetic diseases such as Down syndrome or other congenital abnormalities can be detected.

A detailed ultrasound is an important diagnostic tool for monitoring the health of both the mother and baby during pregnancy, identifying potential problems early, and initiating appropriate treatment when necessary. However, this list is not exhaustive; different structures can be examined depending on the physician's needs. Therefore, it is important to discuss the details with the physician before performing a detailed ultrasound.

How is a detailed ultrasound performed during pregnancy?

A detailed ultrasound during pregnancy involves the same basic steps as a standard ultrasound. However, because the examination is more detailed, a more careful and meticulous process may be necessary. Here are some steps in the detailed ultrasound process:

• Preparation: First, you'll need to prepare for the exam. You'll usually be asked to drink plenty of water and refrain from urinating for a few hours before the procedure. This will help your bladder to be full and allow the ultrasound to obtain a clearer image.
• Examination position: During the ultrasound procedure, the expectant mother usually lies on her back.
• Gel application: Before the exam begins, a water-based gel called ultrasound gel is applied to the abdomen. This gel improves sound wave transmission and helps produce a clearer image.
• Probe application: The ultrasound device's probe (application head) is placed on the abdomen after the gel is applied. The probe is moved by gently pressing on the mother's abdomen, producing detailed images of the baby.
• Imaging and measurements: Images obtained during the ultrasound are viewed on a screen and analyzed by the doctor. The baby's development, organs, size, movements, and other important details are evaluated.
• Removing the gel and finishing the exam: Once the exam is over, the gel is removed from the skin, completing the procedure. You may be asked to empty your bladder.

A detailed ultrasound is important for assessing the health of both the baby and the expectant mother and for identifying potential risks. In each case, the appropriate procedure and the appropriate circumstances will be determined by your doctor's advice.

When is a detailed ultrasound performed?

A detailed ultrasound may be performed at specific times throughout pregnancy, taking into account different circumstances. This ultrasound is typically performed at specific weeks of pregnancy or under special circumstances. However, each situation may vary depending on the needs of the pregnancy follow-up.

A detailed ultrasound is usually performed between weeks 18 and 22 of pregnancy. This is a time when the baby's structural development can be examined in detail and some congenital abnormalities can be detected early. It allows for the examination of the baby's organs, heartbeat, limbs, and other structures.

However, in some cases, a detailed ultrasound may be performed earlier or later depending on specific circumstances. In particularly high-risk pregnancies or if problems have been identified in previous tests, doctors may request a detailed ultrasound earlier.

In any case, your obstetrician will provide the most accurate information regarding when and under what circumstances a detailed ultrasound is necessary. This examination is important for monitoring the health of both the mother and the baby and for identifying potential problems early.

How many hours does a detailed ultrasound examination take?

A detailed ultrasound examination typically lasts approximately half an hour to an hour. This timeframe can vary depending on various factors, including the week of pregnancy, the baby's condition and size, the presence of any suspected medical conditions, and the mother's condition. In cases requiring particularly detailed examination or due to the baby's position or structural features, the ultrasound may take slightly longer. However, it generally lasts approximately 30 to 60 minutes. This timeframe can be extended if the doctor requires more detail during the examination. However, this means that an ultrasound examination rarely exceeds an hour.

In which weeks is a detailed ultrasound performed?

The specific weeks at which a detailed ultrasound is performed can vary depending on a number of factors and is determined by your doctor's recommendation. However, detailed ultrasound examinations are generally performed at the following times:

Weeks 18 to 22 of pregnancy: Ultrasounds performed during this period allow for more detailed observation of the baby's anatomical structure, organ development, and baby's size and position. During this stage, important structures such as the baby's internal organs, limbs, heart, and brain can be examined.

However, in some cases, an early ultrasound may also be performed. In cases of particularly high-risk pregnancies, problems with previous pregnancies, or health concerns, the doctor may request a detailed ultrasound earlier. In these cases, the detailed ultrasound can be performed between weeks 11 and 13 of pregnancy.

Therefore, it is important to consider your doctor's recommendations and the specific circumstances of your pregnancy to give a definitive answer at which week the detailed ultrasound should be performed.

Is detailed ultrasound reliable during pregnancy?

Yes, detailed ultrasounds during pregnancy are generally a reliable medical diagnostic tool. Detailed ultrasound examinations performed by specialists are a common method for assessing a baby's anatomical structure, organ development, and overall health. The information obtained during this examination can provide important clues about the baby's health and development.

The reliability of ultrasound depends on the experience of the specialist performing the procedure, the quality of the equipment used, and the duration of the examination. A properly performed ultrasound can provide detailed images of the baby's organs, bones, brain, heartbeat, and other anatomical structures.

However, it's important to remember that ultrasound cannot detect all abnormalities. In rare cases, an ultrasound examination may be insufficient to detect certain conditions or provide a definitive diagnosis. Therefore, ultrasound results should be evaluated alongside other medical tests and your doctor's clinical assessment before being used as a diagnostic tool. It's also important to remember that detailed ultrasounds are part of routine pregnancy checkups and are often an important tool for monitoring the baby's health.

Is the detailed ultrasonography method performed on an empty stomach?

Generally, there's no need to be on an empty stomach for detailed ultrasounds. There's generally no special preparation required for detailed ultrasounds performed during pregnancy. However, in some cases, your doctor may recommend urinating or drinking plenty of water beforehand. These instructions may be given to improve image quality or, in certain situations, to facilitate a more detailed examination.

Ultrasound is typically performed using an ultrasound probe applied to the skin using a gel. There's no need to be on an empty stomach, but if your doctor has given you any special instructions, it's important to follow them. Your doctor will determine which areas will be imaged during the ultrasound and any preparations you may need.

Can detailed ultrasounds be performed in multiple pregnancies such as twins or triplets?

Yes, detailed ultrasounds can be performed in multiple pregnancies, such as those with twins or triplets. In multiple pregnancies, detailed ultrasounds are an important tool for assessing the development and position of the babies, the health of each baby, and the location of the placenta. In these cases, detailed ultrasounds can play a crucial role in assessing the health and development of each baby, identifying potential risks, and planning appropriate treatment.

In cases of multiple pregnancies, detailed ultrasounds are often performed more frequently. These ultrasounds are important for individually examining each baby and monitoring their development. These examinations can assess their growth rate, organ development, placental status, and interactions. This allows detailed information about each baby's health to be obtained, allowing potential risks to be identified and interventions to be implemented when necessary.
